12 membered Schiff base macrocyclic ligands, 6,7,14,15-tetra phenyl-1,2,3,4, 4a,8a, 9,10, 11,12, 12a,16a-dodecahydro dibenzo [b,h] [1,4,7,10] tetraazacyclododecine L1, and 14 membered Schiff base macrocyclic ligands, 6,8,15,17-tetramethyl-1,2,3,4, 4a,7,9a, 10,11,12,13,13a,16,18a-tetra decahydro dibenzo[b,i] [1, 4,8,11] cyclotetradecine tetraaza L2, 7,16-bis(2,4- dichloro benz ylidene)-6,8,15,17-tetra methyl-1,2,3,4, 4a,7,9a, 10, 11,12, 13, 13a,16,18a-tetra deca hydro dibenzo [b,i] [1,4,8,11] tetra azacyclo tetra decine L3 and 6,8,15, 17-tetramethyl-1,2,3, 4,4a,9a,10, 11,12,13,13a,18a-dodecahydro dibenzo [b,i] [1,4,8, 11] tetraazacyclo tetradecine (7,16-diylidene) bis(methanylyli dene) bis (N,N-dimethylaniline) L4 were synthesized by condensation reaction between diketone and aliphatic diamines. The metal complexes of the types, [ML1Cl2], [ML2Cl2], [ML3Cl2] and [ML4Cl2] [M= Co(II), Ni(II), Cu(II), Mn(II), Hg(II), and Fe(II)] were prepared by interaction of ligands, L1, L2, L3 and L4 with metal(II) ions. The ligands and their complexes were characterized by elemental analysis, magnetic susceptibility, conductivity measurements and IR, 1H and 13C NMR, UV–Vis spectral studies. The thermal stability of the complexes was also studied by TGA analyses. These studies show that all the complexes have octahedral arrangement around the metal ions. We used CB-Dock, a novel blind docking technique that aims to improve docking precision. With the aid of the cutting-edge docking program Autodock Vina, software online, molecular docking studies were used to evaluate the biological significance of the synthesized ligands and identify the probable and efficient binding mechanisms between the various ligands and the active site of the receptor protein. Affinity binding of both Ligand L3 and L4 to Penicillin binding protein 2x (chain B) with PDB 1PYY were much better than to Penicillin binding protein 2B (chain A) with PDB 1WAE due to the presence of hydrogen and halogen bonds. Therefore, they can be more recommended for drug design study to inhibit bacterial growth due their bioavailability. The biological activities of all compounds were evaluated like in-vitro antioxidant activity or percentage free radical scavenging effect via DPPH method against standard ascorbic acid and in vitro anticancer activity via MTT assay against colon cancer cell lines. Results of the biological activities showed that complex CuL3Cl2 exhibited the highest anti-cancer activity against colon cancer cell line i.e. 70.72±6.3 μg/ml among other copper complexes whereas compound CuL3Cl2 showed best antioxidant activity against ascorbic acid i.e. 75.07±1.96 μg/ml. While the biological activities showed that complex CuL4Cl2 exhibited the highest anti-cancer activity against colon cancer cell line i.e. 42.05±7.4 μg/ml among other copper complexes whereas compound CuL4Cl2 showed best antioxidant activity against ascorbic acid i.e. 65.47±1.37 μg/ml.
The current research studies the aesthetic framework for the dialectical development of the functions of the contemporary theater director in an aesthetic approach to the mechanisms of functional overlap between the dramaturgy and direction functions, and scenography and direction, the detection of the controversial structure of that overlap, and what can be summed up in the following question: (what are the aesthetic approaches of the dialectical development in the function of the contemporary theatre director?). The research is determined by a pivotal aim which is (knowing the aesthetic nature of the dialectical development in
The emergence of COVID-19 has resulted in an unprecedented escalation in different aspects of human activities, including medical education. Students and educators across academic institutions have confronted various challenges in following the guidelines of protection against the disease on one hand and accomplishing learning curricula on the other hand. In this short view, we presented our experience in implementing e-learning to the undergraduate nursing students during the present COVID-19 pandemic emphasizing the learning content, barriers, and feedback of students and educators. We hope that this view will trigger the preparedness of nursing faculties in Iraq to deal with this new modality of learning and improve it should t

Objectives: To determine the effectiveness of the instructional program on patients’ knowledge about home safety while receiving anti-cancer treatment at Al- Karama Teaching Hospital in Al-Kut City.
Methodology: A quasi-experimental design is conducted through the application of a pre-test and post-test approach for the study and control groups from February 5th, 2020 to April 25th, 2020. A non–probability (purposive) sample of (50) patients treated at the Blood Disease and Oncology Center is selected and divided into two groups. Each group contains (25) patients as control and study groups. An instrument is constructed that is comprised of two parts; t

Translation is a dynamic and living process that cannot be considered equal to the original text and requires the appropriate structure, language, thought and culture of the target language, and the translator's intellectual, linguistic and cultural influences inadvertently penetrate into the translated text. It causes heterogeneity of the destination text with the source text.
Admiral's theory is trying to help by providing components and suggested approaches to resolve these inconsistencies. In the meantime, in addition to the mission of putting words together, the translator must sometimes sit in the position of the reader and judge and evaluate the translated text in order to understand its shortcomings and try to correct it a

Abstract
The research aims to identify tax exemptions, their objectives and types, as well as to shed light on the concept of sustainable development, its objectives, dimensions and indicators (economic, social and environmental), as well as to analyze the relationship between tax exemptions and economic development, in addition to measuring and analyzing the impact of tax exemptions on economic development in Iraq for the period ( 2015 - 2021) using the NARDL model. The research problem centers on the fact that failure to employ financial policy tools correctly led to a weakness in achieving economic justice, which leads to a failure to improve social welfar

Show MoreThe importance of this research comes from the possibility of achieving positive interaction between accounting and tax through the interest in setting accounting standards and adapting them to local tax legislation, as the adoption of the application of the international standard (IAS 12) for income taxes helps to measure and determine the base for income tax and may lead to an increase in the tax outcome. Through the reliance of enterprises on many accounting bases, and that the tax administration in Iraq depends on the element of personal judgment in determining the tax base, which leads to lack of objectivity in determining the tax outcome, as the impact of the accounting standard (IAS 12) on the tax base and tax outcome is one of th

The researchers chose the annual advertisement of Zain Mobile Telecommunication Company for the year 2020, which shed light on the global Corona pandemic crisis. The idea of the advertisement won wide approval as it focused on the suffering that everyone is witnessing like medical and security personnel in particular, and family relationships consequences.
In addition to the positive global interaction with the message presented by the Company in these exceptional circumstances. The advertisement, which lasted for 2.35 minutes, exceeded 13 million views in a short period of time. This prompted us to choos
